1 Product Overview
1.1 About the RG-AP840-L Access Point
The RG-AP840-L is a dual-radio Wi-Fi 6 wireless access point (AP) developed for indoor
scenarios covering higher education, government, general education, finance, and
business. Compliant with the IEEE 802.11ax standard, the AP works in both 2.4 GHz and 5
GHz frequency bands. It delivers a combined data rate of 5.375 Gbps, with up to 575
Mbps in the 2.4 GHz band and 4.8 Gbps in the 5 GHz band. This eliminates the
performance bottleneck.
The RG-AP840-L provides wireless network security, RF control, mobile access, QoS
guarantee, and seamless roaming. It works with a wireless access controller to perform
data forwarding, security, and access control for wireless users.
The RG-AP840-L complies with IEEE 802.11n/ac/ax concurrently. The AP can be installed
on a ceiling or wall. The RG-AP840-L adopts either local or PoE power supply. Users can
flexibly select power supply modes based on various scenarios. The AP is an ideal choice
for the scenarios including large-scale campuses, enterprise offices, and Wi-Fi hotspots.
1.2 Hardware Features
The RG-AP840-L provides two RF connectors, two electrical ports (LAN1 port supports
PoE power supply in compliance with IEEE 802.3af/at/bt, and LAN2/IoT port can supply a
maximum power of 12.95 W (48 V/1 A) to IoT units), one 5GE SFP port, one RJ45 console
port, one power socket, one USB port, and one Reset hole.
